Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless Community. Java is known for its high cold start times and high memory footprint. For both you have to pay to the cloud providers of your choice. That's why most developers tried to avoid using Java for such use cases. But the times change: Community and cloud providers improve things steadily for Java developers. In this talk we look at the features and possibilities AWS cloud provider offers for the Java developers and look the most popular Java frameworks, like Micronaut, Quarkus and Spring (Boot) and look how (AOT compiler and GraalVM native images play a huge role) they address Serverless challenges and enable Java for broad usage in the Serverless world.

The purpose of Serverless is to focus on writing the code that delivers business value and offload undifferentiated heavy lifting to the Cloud providers or SaaS vendors of your choice. Today’s code quickly becomes tomorrow’s technical debt even if you meet the perfect decision. The less you own, the better it is from the maintainability point of view. In this talk I will go through examples of the various Serverless architectures on AWS where you glue together different Serverless managed services relying mostly on configuration, significantly reducing the amount of the code written to perform the task. Own less, build more!

This document discusses using Ansible to implement continuous delivery of infrastructure configuration. It introduces Ansible as an infrastructure management tool that allows infrastructure to be defined as code in playbooks and executed across servers. Using Ansible, infrastructure can be provisioned and configured in an automated, repeatable way to support continuous delivery practices and reduce risk. The document provides examples of using Ansible to set up a sample pizza ordering application infrastructure.

When we talk about prices, we often only talk about Lambda costs. In our applications, however, we rarely use only Lambda. Usually we have other building blocks like API Gateway, data sources like SNS, SQS or Kinesis. We also store our data either in S3 or in serverless databases like DynamoDB or recently in Aurora Serverless. All of these AWS services have their own pricing models to look out for. In this talk, we will draw a complete picture of the total cost of ownership in serverless applications and present a decision-making list for determining if and whether to rely on serverless paradigm in your project. In doing so, we look at the cost aspects as well as other aspects such as understanding application lifecycle, software architecture, platform limitations, organizational knowledge and plattform and tooling maturity. We will also discuss current challenges adopting serverless such as lack of high latency ephemeral storage, unsufficient network performance and missing security features.

This document provides an overview and examples of Amazon Web Services' (AWS) DevOps Guru and CodeGuru services. DevOps Guru uses machine learning to detect operational issues from metrics before they impact customers. CodeGuru provides code quality recommendations and identifies inefficient code. The document demonstrates how both tools integrate with services like DynamoDB, API Gateway, Lambda, and PagerDuty. It also compares CodeGuru to SonarQube.

This document discusses conducting user research for an API management product. It outlines the research process of empathizing with users through interviews and personas, defining problems by synthesizing findings, ideating solutions through design studios, and prototyping and testing solutions. The research uncovered that API consumers want easy discovery and secure access to APIs without involving operations. It also found that API managers want observability into API usage. Outcomes of the research included API discovery and documentation pages and secure access pages. The value of user research is building empathy, validating assumptions, and providing structured feedback.

Isomorphic JavaScript applications can share the same code and run on both the front end and back end. It is also a spectrum containing applications that share minimal bits of validation logic with ones that share a bulk of the application code. Nashorn is a new JavaScript engine for Java that was released with Java 8. The Nashorn JavaScript engine makes isomorphic web apps on the JVM possible by allowing the exact same browser code to run on the server. This enables us to achieve the don’t-repeat-yourself (DRY) principle, by reducing repetition in a multitier architecture. This presentation covers the key concepts, rationale, and categories of Isomorphic JavaScript and how it makes your large applications maintainable.

The document discusses using Dynacache with WebSphere Extreme Scale (WXS) to improve the performance and scalability of caching for WebSphere Application Server (WAS) applications. WXS provides a "drop-in" cache that can be used instead of the default WAS caching without code changes. This allows the entire WXS grid to act as the cache, providing better scalability. Key benefits include better performance through caching of expensive operations, leveraging the power of a distributed cache architecture, and increased flexibility and capacity for large applications.

This document discusses patterns and best practices for dependency injection using the Contexts and Dependency Injection (CDI) specification.

This presentation provides an introduction to the (subjectively) most useful tools for debugging on Windows.

Native out-of-memory errors happen when a Java application runs out of memory, not in the Java object heap but outside it. The cause may be memory use for native libraries, class loading, multithreading, working data for the Java VM, backing storage for Java objects, or other reasons. No single tool can give you all the answers, and we need to cross-reference information from multiple sources to isolate a problem. Operating system tools, Java dumps, logs, and debuggers all provide useful perspectives, and your challenge is to line them up to see the whole picture. This session works through the tools and data available on the main server platforms to give you a repeatable framework for native out-of-memory error debug.

The Liberty Buildpack aims to remove the hassle of running Java applications on Cloud Foundry whether it is the simplified setup, auto-configuration of Liberty and Java EE references to cloud resources, reduced droplet size through selective provisioning of the runtime, or the zero-touch configuration and usage of services. There are times, however, when an application needs a feature that the buildpack does not yet provide. This talk will start by showing how to use and configure the Java buildpack and finish by showing how to extend the buildpack to ensure that IBM BlueMix Cloud Foundry is the best place to run your application. To build services and integrate them with BlueMix, you must implement the Service Broker API of Cloud Foundry for your services. This talk will explain how to write plugins to the Liberty Buildpack that will auto wire services your organization developed and integrated into CF making it easier for your apps to use the services in Cloud Foundry.

This slide deck describes some of the architectural principles behind the Heroku, OpenShift, Cloud Foundry and BlueMix enterprise PaaS. The commonalities and differences in designing and porting apps across these platforms to Cloud Foundy/BlueMix are explored.

The document discusses how startups can build scalable applications without servers by leveraging serverless architectures on AWS. It describes how Dean Bryen challenged himself to build an image processing microservice within 45 minutes using only AWS services like Lambda, API Gateway, S3, and DynamoDB without any servers or monolithic code. The microservice included a static site in S3, an API built with API Gateway that triggers a Lambda function for image processing, and stores results in DynamoDB. This demonstrated how platforms services can provide high availability and scalability without the need to manage infrastructure. The document also discusses how Gousto evolved from a monolithic PHP application to a microservices architecture using Lambda and other AWS services.
